AI Technical Summary

Technical Problem

Existing solid-liquid separators have poor pressure regulation flexibility, making it difficult to adapt to solid-liquid mixtures with different viscosities and particle sizes. This results in low separation efficiency, severe equipment wear, inconvenient cleaning and maintenance, and affects continuous operation.

Method used

An adjustable component for the distance between the driven and driven rollers was designed. Combined with the initial separation by the inclined screen and the cleaning by the scraper, multi-stage separation is achieved. The feed speed is controlled by the return port and the backwashing device is used to prevent clogging. The modular design facilitates maintenance.

Benefits of technology

It achieves efficient separation of solid-liquid mixtures with different viscosities and particle sizes, reduces equipment wear, improves separation efficiency and equipment life, and reduces downtime and maintenance costs.

Abstract

This utility model relates to the technical field of sewage treatment devices, and more particularly to a solid-liquid separator. Its technical solution includes a frame and a housing mounted on the frame for the separator assembly. The separator includes an inlet for introducing a mixture of water and solid waste, and a drive device for compressing the solid and liquid components. The drive device includes a drive motor and a drive roller connected to its output end, and a driven roller positioned above the drive roller. One end of the driven roller is equipped with an adjustment component for its height position. This utility model achieves precise pressure adjustment, adapts to different materials, utilizes an inclined screen and roller pressing structure to achieve multi-stage separation, facilitates material cleaning, prevents overflow and clogging through reflux and interception design, has a stable structure and modular maintenance, and comprehensively improves separation efficiency and equipment performance.
